5.3.18 EEPROM data
This function enables the EEPROM data to be checked and data written by specifying
the EPPROM address directly, even when an error has been triggered. (However, this
function cannot be used when the CPU in the main logic circuit, the I/F receiver, the
RAM or the EEPROM have been damaged.) The following menu will be displayed
when a tick has been added to [EEPROM Data] on the supplementary menu.
Figure 5-36. EEPROM data
The EEPROM data function contains the following two functions:
V
Check the EEPROM Data
This enables the EEPROM data within a range specified by an address to be
confirmed.
V
Change the EEPSOM data
It is possible to write data into specified EEPROM addresses, and amend existing
values. However, this function should only be used under special circumstances.
Note that there is a possibility of trouble occurring if the data is amended to
incorrect values.
